otrMPING-CAR,

To all 'whom it may concern: t

Be it known that I', CrrAnnEs B, DAwsoN, `a citizen of the United States, residing at Fulton, in the county of Oswego and State of New York, have invented cer/tainl new and useful Improvements in DuiI ing-Cars; id I do herebydeclare the fo lowing to be a `ful/l, clear2 andeXact description of the inlivention, such a will enable other-s skilled in' i; the art to which it appertains4 to make and yuse the same. ,Y

My `inventionrelates to dumping cars of the class in which the car body 'is 'arranged to swing Jlaterallyfsoas to dump the lafd on one side or the other, and has for its object to provide a l construction by which the car body, when in dumping position, will swing of its center toward theside on Which the loadvis to be dumped, thus throwing the load Vfarther fromthetracks than does adump;

l ing car of 4ordinary construction,i and which will relieve the tendency to push the car truck from .the tracks while dumping, and

will cause the car to ride more steadily. [With these and other objects hereinafter more fully explained, my invention consists in the construction and combination herein-4 after set forth and claimed. I,

Referring to the drawings-Figure 1 is an end view of a car embodying my invention, the, car being shown in dumpingA position;

Fig. 2 is asimilar view, showing the car body in position to receive its load, and Fig. Sis a side view of the car. Fig. 4 iis' a side elevation of a dumping car, and Figs. 5 and 6 are detail perspective views of the double hinge.

'In the drawings'l isa nsillextending longitudinally of the car truck midway between the wheels, supported by the cross' sills 2, the ends of which in'turn are supported b lthe car axles in any usual or convenien manner. At suitable intervals the longituu dinal sill is vprovided with blocks 3, the upper ends of which are formed with a central re cess 4, extending in a direction across the longitudinal line of \the car, and with a semi-cylindrical boss. 5 at one end and -a semi-'cylindrical recess 6, with its outer wall cut away, as shown at 7 at the other end, and a flat face 16 between the boss and the l, l'eCeSS-- Specicatin of Letters Patent.

blocl 3, and having at one end' a semi-cyf lindrical recess `l0, having its outer wall cut ,away at 1.1, and at its 'other end having a 13 betwee the recess and the boss", the two blocks 3 and 8 beirfg adapted to lit together the recess 10 of the upper block fitting over theboss 5 of the lo-'ygferblock and the boss 12 of the upper-block, fitting into'the recess 6 of the lower blokf. The-bosses 5 land 12 .each have a hole at their centers. toreceive a pin 14, the pins 14 being connected by a link 1,5,.which isreceived in the recesses 4 and 9. NVh'en the carV body is in position to receive its load,A or the ca r is moving or resting on thetraclr, the upper block 8 rests throughout its extent on the block 3, the re; cess 1Q resting'on the boss 45, the flat face 13 resting on the flat face-16, and the boss 12 restlng on the recess `6, so that a broad sup'- port is aifordedwithout tendency to rock. When the load is to be. dumped, the opposite side of thefcr body to that on which the.

load is to be deposited is raised, the body s turns on one end or 'the other of the doubl e\\g hinge formed by the blocks 8 and 8,l the pin-s the center on' which the car bodyI turns-in dumpingis away from the longitudinal central line of ,the car, the side of carbodyo-n they side onwhich the load is to de osited will be thrown outward farther t an it serve as means for insuring the/foar body from accidental tipping, the broad surface of the blocls 3 and 8 being suicient under ordinary circumstances tomaintain the body against tipping.

While the construction above described 1s of any desired construction, I prefer to use it in connection with the car body shoWn, -in which the side' gates on the side onwhich the load is to be dumped are automatically car bodyv upright, in my constructionpthey adapted for use with a truckand car body semifcylindric'albosfs 12,'and witli'a flat face.

14 preventing possible?disarrangement. As

would if the turning center were in the cen v raised asrgthe car body is inclined, to effect the dumping. The device by which this is effected' consists of arms 20, `pivotedrat 21 Imidway between the sides of the car near its upper edge, having the side gates 22 pivotallyv connected to their outer ends. To the arms 20, between their ends, are pivotally connected links 23, arranged to telescope with links 24, pivoted at their lower ends to arms 25, which extend outward and upward from the car truck,v the arrangement being suchthat as the car is tipped in dumping, the links 23 and 24 on the side on which the load is to be dumped will hold the ar1ns^20 up, sothat theside gates 22 will be Withdrawn, while on the other side of the car the linkv 24 will be drawnrou/t of link 23, thus permitting that side of the car body to rise. When the side gates of the car are in closed position they are retained against outward swing by arms 26. By reason of the pivotin of the side gates 22 to the arms 2l, they wi l readily returnV to normal position after dumping.

The latch 27 is pivotedy at 28 to the end of the car, and is held in locking position by a loop 29. `'To lock the safety chain 18, its loop 19 is yslipped over the latch and the latch then swung upward on its pivot until its end is against the end of the car, in which position it is held by loop 29. By this arrangement the upward movement of the latch tightens the chain.

Having thus described my invention,what Iclaimis:

1. In a dumping car, a double hinge connection between the car body and truck comprising an uppenand a lower block, each having at one end a semi-cylindrical boss l and at the other end a recess adapted to receive the boss on the other block, ya pin exseat in said longitudinal recesses when the plates are in horizontal relation, as set Iforth.

3. A dumping car having a truck and a body, a stationary plate and a pivotal plate, the adjacent faces of the plates having each a concaved transversely disposed recess near one end and projections which arevspaced apart, the ends of the latter being convexed, the projections upon one plate adapted to engage the concaved recess in the other plate when the plates are in horizontal relation, the innery face of each plate intermediate the concaved projection and the recess being parallel with the outer yface of the plat/c, the inner face of each plate having 'a central longitudinal slot intermediate said projections and intersecting the recess, pins passing through registerino apertures in the projections upon each ikp ate, and a link mounted pivotally at its ends upon said pins and'adapted to engage'the recesses upon the two plates when the latter are in their normal positions, as set forthw In testimony whereof I aiiix my signature in presence of two witnesses.
